Dynamical systems study in single-phase multiferroic materials
Electric field induced magnetization switching in single-phase multiferroic
materials is intriguing for both fundamental studies and potential
technological applications. Here we develop a framework to study the switching
dynamics of coupled polarization and magnetization in such multiferroic
materials. With the coupling term between the polarization and magnetization as
an invariant dictated by the Dzyaloshinsky-Moriya vector, the dynamical systems
study reveals switching failures and oscillatory mode of magnetization if the
polarization and magnetization relax slowly during switching
